“…Six of the substrates tested in this study were within the established range, and due to this characteristic, they can be considered potential substrates for use in agricultural production. This parameter is susceptible to being corrected, so that in the substrate, it becomes a variable to be considered manageable, because it can be corrected during cultivation with the application of a nutrient solution with an acidic pH [32]. Similar results were found in the literature, where, depending on the origin of the waste, there were different pH values that may or may not be within the desired range [11,33].…”

Agricultural production activities generate a large amount of waste, most of which is of organic origin from plant remains. These residues could easily be transformed into a resource, specifically, into a substrate for use in soilless cultivation; however, in most cases, they are not used. Therefore, a characterization of local agricultural residues was carried out to determine their use as a substrate for crop cultivation without soil in a protected environment. The selected substrates were Sphagnum peat, coir fiber, and compost, which were managed alone or in mixtures of 50/50, 75/25, or 25/75% v/v ratios. We also included a mixture of virgin mountain soil and earthworm humus (known as INIA mixture) because it is used by local growers. The results showed that the substrates based on coir fiber, peat, and mixtures of both presented suitable characteristics for horticultural crops. On the contrary, compost-based substrates had high pH values and low organic matter contents that could be improved before use. The relationship found between the evaluated parameters of each substrate allowed us to establish that variables, such as the content of organic matter and water at different tensions and particle sizes, can be utilized to make a quick selection of the substrates produced locally, which would lead to the use of waste in a way that is more consistent with sustainable agricultural production and minimal environmental impact, by being used in the production of crops in containers without soil. In addition, these results can be used as an alternative reference in localities where these residues are easily available.

“…The inclusion of sand in the substrates has multiple benefits in agave production. For example, it improves some parameters, such as aeration, moisture retention capacity, cation exchange capacity, pH, and electrical conductivity (Gayosso-Rodríguez et al, 2018;Acevedo-Alcalá et al, 2020). Substrate quality is related to the chemical characteristics that compose it, mainly the balance and availability of macronutrients, especially those derived from nitrogen (N), phosphorus (P), and potassium (K) (Hernández et al, 2018).…”

Mexico has 159 species of Agave spp. In the agri-food industry stand out are Agave tequilana, A. angustifolia, and A. salmiana. A limitation to producing maguey seedlings is the low availability of organic substrates that favor plant adaptation in the field. The objective was to evaluate the effect of nitrogen (N), phosphorus (P) and potassium (K) found in substrates in response to vegetative and root growth of A. salmiana in agricultural areas of Huichapan, Hidalgo, Mexico. The treatment consisted of earthworm humus (EH) and leaf compost (LC) substrates with materials from the region with different percentages of EH (100, 75, 50%), LC (5, 10%), and sand (20, 40%). The treatments were applied with 14 random replications in two phases in seeds and 40-day-seedlings. The variables evaluated were NPK amount and pH in substrates. The physiological variables measured were plant height, leaf number, stem diameter, root length, and volume. Significant differences (P?0.05) were observed in seedling physiology due to the effect of the treatment. The best agronomic responses (plant growth and root length/weight) of Agave seedlings were T5 (75% earthworm humus + 20% sand + 5% leaf-soil) and T6 (50% earthworm humus + 40% sand + 10% leaf-soil); in both treatments, the NPK percentages were different from the control (Haplic Phaeozem soil) group. The final concentration of NPK in T6 was N = 0.04%, P = 398.13 mg Kg-1 and K = 11.88 meq 100g-1. The results infer that NPK availability in soil and progressive acidification (initial pH = 8.6, final pH = 7.4) of the substrate can favorably influence the plant response. The interactions between NPK availability in the substrate and their use for a better response in maguey seedling adaptability open up new lines of research on the productive systems in the region of Huichapan, Hidalgo, Mexico.

En las últimas décadas se ha generado el interés por integrar los residuos agroindustriales y de cosecha en la producción agrícola en sistemas de producción intensivos, para disminuir el impacto ambiental y los costos de producción. Por ello, el objetivo de esta investigación fue caracterizar química y físicamente algunos residuos agroindustriales y de vegetales disponibles localmente en el estado de Tabasco México, para conocer su uso potencial como componentes de sustratos agrícolas. Se caracterizaron propiedades químicas y físicas de materiales orgánicos: pH y CE, granulometría, diámetro medio de partícula (Dm), densidad aparente (Da), porosidad total (Pt), capacidad de aireación (CA) y porosidad de retención de agua (Pra), y se determinaron las curvas de retención de humedad. El pH de los materiales analizados osciló desde 5.1 hasta 10,44, la CE fue menor a 2 dS·m-1 excepto para el lirio acuático y la fibra del raquis de plátano. La granulometría de los materiales analizados tuvo más del 25 % de partículas menores a 0,85 mm; no obstante, la viruta de teca y la cascarilla del fruto de palma de aceite tuvieron un Dm de 5,67 mm y 3,21 mm, respectivamente, lo que incrementó su capacidad de aireación. El aserrín de pino y la cascarilla de fruto de cacao tuvieron valores superiores al testigo en Da, Pt, Pra, CA y agua disponible total. En conclusión, los materiales tienen diferentes características de aireación y retención de humedad, y se pueden combinar en distintas proporciones de acuerdo a las características físicas e hidrofísicas particulares y generar un equilibrio en la relación agua-aire.
